A library that converts between azimuth and quadrant bearings, calculates the chord distance for a curve given arc length and radius, and calculates latitudes and departures of a traverse.

I think this is a calculator eating virus that just ate my 50G

Sorry to hear that. I have used this library in both 49g+ and 50g without any problems.

Its cool, i had almost everything backed up so i could restore pretty quick. but i didnt backup my 50G port of the AZ48 program or all my work on calculating sun ephemeris. so my crash just ruined allot of hard work.
So now I'm looking for a good backup utility..
